DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 495,096, dated April 11, 1893. Application filed November 13, 1891. Serial No. 411,788. (No model.)

My invention relates to certain improve ments in dumping wagons, having for its object the construction of a detachable wagonbody, with its bottom divided lengthwise and the sections pivoted on longitudinal rods supported by the bolsters, whereby the contents of the body may be quickly and conveniently discharged.

My improvements are fully described and illustrated in the following specification and the accompanying drawings,and the novel fea tures thereof specified in the claims annexed to the said specification.

In the accompanying drawings representing my improvements in dumping wagons, Figure 1 is a plan view of a wagon-body embodying my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation of the same. Fig. 4 is a transverse section on the line 4-4, Figs. 1 and 2. Fig. 5 represents the manner ofinserting the supporting rods in the lower bolster.

My improved body for dumping wagons, consists essentially of the sides A A, the endboards B B and the pivoted bottom-sections O C. The body is supported on the bolsters D E, D E, which rest on the usual bolsters of any suitable wagon, when the invention is in use,the ends of the bolsters being provided with slots or notches, 0 0, for the reception of the ordinary stakes. It will thus be understood, that my improved wagon body may be used on any ordinary wagon, and that it may be readily applied thereto or removed therefrom,being made of dimensions suitable for any particular case. The bottom sections 0 O are supported by the rods F F and the chains H H attached to the rods I I, so that the outer edges of the sections, may be dropped downward, as represented by the dotted lines 0, in Fig. 3, for the purpose of discharging the load from the wagon body. It will be observed that the rods F F are placed at a distance on each side of the central line of the body,the results being the partial balancing of the load on each of the bottom sections C C, so as to reduce the amount of the weight supported by the chains, and the avoidance of any construction rerembling a hinge or joint at the center, which would become clogged by dirt or the material constituting the load. The bottom-sections have attached -to their lower sides the cross bars J J, through which the rods F F pass, and which extend outward beyond the sections to afford room for the attachment of the bolts or eyes, 4", to which the chains are connected.

The lower sides of the bottom sections 0 0', rest on the rods F F,the holes in the crossbars for the rods being made in such positions as to secure this result, whereby the sections are prevented from being bent downward by the load. The cross-bars are secured to the bottom sections by bolts or screws. It willbe observed from Fig. 4,thattheinner ends of the cross-bars are shortened, leaving a space between them as shown at s, Fig. 4 so as to permit them to swing upward without coming in contact with each other and for the purpose of allowing the material of the load to pass through between without clogging. The crossbars J J may turn on the rods F F, but I prefer that the rods themselves should turn in the notches t t in the lower bolsters E E. These notches are formed as represented in Fig. 5, by cutting out a portion from the upper surface of the bolster so that the rods may be readily inserted or removed,this arrangement providing for the removal of the whole body except the bottom sections at once,- the lower bolsters E remaining on the Wagon after the bottom sections have been removed. The upper bolsters D D are attached to the side-boards by the straps '11 2;, which pass through the upper bolster and are provided with nuts below it,their upper ends being secured either directly to the sides or to the cleats 16 which are used to hold the end boards in place. It will thus be observed that the upper bolsters are permanently secured to the body, so that they remain always at the same distance from each other,thus preventing the bottom sections from jamming at the ends against the bolsters, and preserving their freedom of motion. It will also be observed ICO that the upper bolsters project inward a short distance inside of the end boards and the lower bolsters, so that the movable sections 0 0 cannot at any time come in contact with any of these parts. The cross-bars J J are made tapering from the inner ends outward, thus securing sufficient strength below the rods F F.

The lifting rods I I are attached to the outside of the side-boards A A by suitable brackets, L L in which they are arranged to turn. At one end,preferably the rear,-the rods I 1 are provided with the hand-wheels, N N, the ratchet-wheels O O, and the pawls P P. As indicated in Figs. land 2,the sides are extended beyond the end-board, and support the rods I I by suitable brackets R R. The object of this construction is to bring the hand-wheels out of the way of the Wagonwheels. The pawls, which may be provided with a handle Q, by which they are operated, are pivoted on the brackets R R. The ratchet-wheel may be cast in one piece with the corresponding hand-wheel. The chains H H are attached at their lower ends to the outer extremities of the cross-bars J J, and at their upper ends to the rods I I, by pins orscrews. When the rods are turned in the proper directions, the chains are wound up on or unwound from them, thus raising or lowering the dumping-sections C C. When the sections are raised and the bottom of the body.

closed up, as shown by the full lines in Fig. 4, the chains are wound up on the rods, and the pawls P engage with the ratchets O, holding the bottom-sections in place against the sides of the body, and sustaining any load which may be placed therein. The rods F F and I I are conveniently made of pipes, as indicated in Fig. 5. y

The manner of operating 'my improved dumping wagon will have been already understood from the preceding description. The load is dumped by disengaging the pawls from the ratchets on the side-rods, and allowing the outer edges'of the bottom-sections to fall downward,an operation which is easily formed even with acomparativelysmall handwheel, in consequence of the fact that a portion of the load is balanced on the supporting rods. wagon is prepared for another load by turning the side-rods so as to wind up the chains thereon, and engaging the pawls With the ratchets, thus securing the bottom-sectionsin place against the sides in position to support any weight placed in the body.

My improved dumping wagon is cheap in construction and thoroughly durable and convenient in use, as I have demonstrated by practical trial.

I am aware that bottom sections have been pivotally supported near the longitudinal center of a wagon body bottom and such matter is not broadly of my invention. In such prior constructions however the sections were hinged or pivoted at their rear edges so that The load having been dumped, the

no counterbalancing effect of the load at the center was utilized as. in my improvement; and furthermore the hinge or pivot supports required a central beam or roof shaped strip either to protect the joint or to support the hinges which beam obstructed the Wagon body bottom. My sections are pivoted at a considerable distance from their rear edges which latter receive directly a considerable part of the weight of the load, and my supporting rods and the inner ends of cross bars J J are normally separated a considerable distance to provide a clearing space 3 so that they are free from liability to obstruction at that point either in opening or in. closing the sections.

I claim 7 l. The herein described dumping wagon, provided with a bottom divided lengthwise consisting of the movable sections 0 O, pivoted on the longitudinal rods F F and with means for holding the bottom sections in place to carry the load, the rear edges of said sections extending back of the rods and bein g unobstructed above, whereby they sustain a part of the load to partially counterbalance the weight on their front portions, substantially as described.

2. The combination with the body of a dumping wagon, of the longitudinally divided bottom consisting of the movable sections 0 G, longitudinal rods F F, bolsters D D, E E, said bolsters D D being attached to the wagon body and bolsters E E attached to the running part of the wagon and means for holding the bottom in place to carry the load, substantially as described.

3. The combination with the body of the dumping wagon, the movable sections 0 O pivoted on the longitudinal rodsF F, andthe bolsters D D attached to the body and bolsters E E, provided with notches for the ends of the rods, whereby the body can be lifted from the sections and the latter from thebolsters E E, substantially as described.

4. The combination with the body of a dumping wagon, of the movable bottom sections 0 C, the longitudinal supporting rods F F, the cross bars J J extending beyond the sides of the body, the bolsters D D and bolsters E E, rods I I flexible connections H H, and suitable ratchets and pawls,substantially as described.

5. The combination with the body of a dumping wagon, of the divided bottom consisting of the movable sections 0 O, pivoted on the longitudinal rods F F, arranged on each side of the central line, and the cross bars J J, having an open space s between their inner ends, said bars being shorter at their inner ends within the rods than the corresponding portions of the sections to leave a space 8, substantially as described.
